RADIUS user roles and the Service-Type attribute

The Service-Type attribute defined on the RADIUS server, results in the following user role assignment on the switch:
Service-Type User role assigned Description
Not set None (authentication error) Service-Type not set, so the user is denied access.
7 NAS-Prompt operators Map the user to operators role as RADIUS Service-Type 7.
6 Administrative administrators Map the user to administrators role as RADIUS Service-Type 6.
Other than 6 or 7 None (authentication error) As per RFC 2865, NAS does not need to be implemented with all Service-Types. It treats unsupported Service-Type as Access-Reject.
